Oil Cooler, how many installed it & was it worth it?

This is a discussion on Oil Cooler, how many installed it & was it worth it? within the Yamaha YFM350 Raptor/Warrior ('87-Present) forums, part of the Performance /Technical category; I'm thinking about adding the oil cooler to my warrior but before I get into all the work I was wondering if it made any ...

If you look how specwarrior did his oil cooler install it was much easier than having to remove the side case and drill. his cooled the oil good.

if you do the oil cooler like he did just make sure you have good protection of the oil lines. and that would be the same for the other hookup as well. you dont want to get out and have a stick or rock hit a line and brake it.

Regardless of how you choose to install a cooler, it is a good idea to have one. It isn't AS neccessary with an internally stock motor, but it still helps on those hot days ESPECIALLY if you are operating alot at high revs and low speeds (hill climbing, dunes, etc...).

This isn't something where you will notice a performance gain, but will help prevent overheating and performance loss.

Can you post a guide or something spec? Just curious how you did yours.

this is mascmans way and if you look at an older big bear 350 there is an oil cooler on it. There is a cover attached where the normal oil filter cover goes. It has fittings on it that will go to your cooler and then return back to the cover. You can go to a yamaha dealer and look on the fish for part numbers (however fish is spelled ) You can order new parts or find some on ebay, but a lot of other are looking too. I myself have the mascmans style cooler, I like it so far but either way will work.

Anyone have pics of that Big Bear oil cooler set up on a Warrior. There doesn't look like there would be enough room for the Big Bear oil pump cover, being so tight next to the stator on the Warrior. I'm there if it can be done.

Sorry To Jump In On This thread but I'm in need of more info on the oil cooler mod for the Raptor warrior ATV. I have a question about your oil cooler mod on Step 6 it says to put putty in the galley between the holes witch holes in the galley is it talking about. the two holes we just drilled or the galley hole in the inside and the hole we drilled to line up with the little galley hole.

i did it just for my high compression pistin, i went with mascmans style, workes great!

like spec said u dont get any more performance, but it will help ur bike perform longer, and improve the life of ur motor
